Things to check before posting problems
1-Shut down all non-essential background applications that are running in windows before launching the installer. (This would include disabling any type of burning software that you may use which can interfere with the EAW Demo).
2-disable any virtual drives that you may have on your computer.
3-disable any download managers that you have running in the background.
4-Make sure you have the latest video and sound card drivers installed on your computer.
5-Make sure your demo after download is around 740 MB in size.
